ABSTRACT:
A pneumatic tire reinforced by a reinforcing belt is provided, the reinforcing belt having at least one cord reinforced ply, and, in turn, the cord reinforced ply having a plurality of substantially parallel spaced apart elongated cross-section reinforcing cords. The ply may be a bias ply in which the reinforcing cords are disposed at a bias angle, or it may be an overlay ply being axially longer than any other plies and having curving ends which overlay and curve over the ends of any other plies to strengthen shoulder portions of the pneumatic tire. Preferably, in the case of an overlay ply, the reinforcing cords are disposed substantially circumferentially. Preferably also, the elongated cross-section of the reinforcing cords is elliptic; and, the reinforcing cords are thermoplastic monofilaments formed by extrusion.
